Description
@if
directive in Sass is useful to test for a specific case - it works just like the if
statement in JavaScript.
@mixin make-bold($bool) {And just like in JavaScript,
@if $bool == true {
font-weight: bold;
}
}
@else if
and @else
test for more conditions:
@mixin text-effect($val) {
@if $val == danger {
color: red;
}
@else if $val == alert {
color: yellow;
}
@else if $val == success {
color: green;
}
@else {
color: black;
}
}
Instructions
mixin
called border-stroke
that takes a parameter $val
. The mixin
should check for the following conditions using @if
, @else if
, and @else
:
light - 1px solid black
medium - 3px solid black
heavy - 6px solid black
none - no border

tests:
- text: Your code should declare a <code>mixin</code> named <code>border-stroke</code> which has a parameter named <code>$val</code>.
